旋转DSA及三维重组技术在颅内动脉海绵窦瘘诊断中的应用价值

The Application of Rotational Digital Subtraction Angiography and 3D Reconstruction Technique in Diagnosing of CCF

目的评价旋转DSA及血管三维重组技术在颅内动脉海绵窦瘘诊断中的价值。资料与方法20例单侧眼球突出患者(除外非动脉海绵窦瘘疾病)应用传统DSA,旋转DSA及血管三维重组进行检查,对比不同方法对动脉海绵窦瘘病变的显示情况。结果20例患者均确诊为动脉海绵窦瘘,常规DSA不同体位均能显示病变部位及范围,但对于瘘口的位置、数目以及与病变动静脉之间的关系均不能显示。旋转DSA显示动脉海绵窦瘘结构的能力较常规DSA明显提高。所有血管三维重组的图像都清晰显示了瘘口的位置、数目以及与病变动静脉之间的关系。结论旋转DSA及血管三维重组技术对颅内动脉海绵窦瘘病变结构显示极佳,尤其是三维重组技术,明显有助于对颅内动脉海绵窦瘘的诊断和介入治疗。

Objective To evaluate the value of rotational digital subtraction angiography（RDSA） and three dimensional （3D） reconstruction technique in diagnosing CCF. Materials and Methods Twenty patients with exophthalmus underwent conventional DSA, RDSA and angiographic 3D reconstruction. The two techniques were compared to find the effectiveness in showing the CCF structures. Results All the patients were confirmedby angiography. Detailed structurs sueh as the positions and numbers of orificium fistulae, the relationship of ateries and veins were difficult to identify on conventional DSA, whereas these details were shown clearly on RDSA and 3D reconstruction techniques. Conclusion RDSA and 3D reconstruction techniques, especially the latter, are effective and useful in diagnosing and interventional therapy for CCF.
